If you are into art at all, this is the site for you. It is amazing how many spectacular artists are on this site. You can start from the homepage and view random popular works, but my favourite is to look at the daily deviations or search for a topic, find the one I like the best, look up the artist, then look at their favourites. If you do this, generally the favourites of an artist that you really like the style of will be packed with amazing similar pieces. This way you can find an artist or photographer that you really like and if you are lucky they have several hundred of their favourites for you to browse.
You have to avoid the nudes and anime, but when you find some artists you like you can even +watch them if you have an account, so you can login from time to time and check out new pieces from your favourites. You can even contribute yourself, look for feedback, earn llamas, etc.
Give it a try! There is everything from amazing photography, digital art, hobbies even poetry.
